Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 993780, here are decompositions:

17 + 993763 = 993780
97 + 993683 = 993780
101 + 993679 = 993780
163 + 993617 = 993780
191 + 993589 = 993780
223 + 993557 = 993780
239 + 993541 = 993780
313 + 993467 = 993780

Showing the first eight; more decompositions exist.
